CADENCE SIP RF LAYOUT While system-in-package (SiP) design makes it possible to combine RF and analog content on the same substrate, it presents a number of challenges. These include designing and integrating RF/analog chips with substrate-level buried RF passive devices as well as enabling top-level pre- and post-layout circuit simulation of the entire SiP design. Cadence SiP RF Layout provides the proven path between Virtuoso analog design/simulation and substrate layout. It enables layout designers to implement a SiP RF design that includes RF/analog die, embedded RF discretes, constraint-driven interconnect routing, and full SiP tapeout manufacturing preparation.
